Hello Arie;
This elegant solution relies on ". of any list of spaces matching 0#0
instead of a VALUE ERROR. Perhaps this should be included in the
documentation, since spaces are not a verb, adverb nor conjunction.
This ((0#0)-: ".' ') is my J nugget of the day.

I'm most interested in an elegant way to rephrase sum-of-the-digits:
+/@:,@:(#.^:_1)
Can you come up with a better way? Example:
10 +/@:,@:(#.^:_1) 10 3 112 16 7 22
